This application claims the benefit of U.S. Provisional Patent Application No. 61/607,411, filed on Mar. 6, 2012, which is hereby incorporated by reference for all purposes as if fully set forth herein.

BACKGROUND OF THE INVENTION Field of the Invention

The invention generally relates to a medical device, method and system thereof for the placement or passage of patches, sutures, anchors, tags, tissue sensors and more particularly to a medical device for repairing female pelvic organ or tissue prolapsed region.

Discussion of the Related Art

It is estimated that nearly twelve percent of women will need surgery for pelvic organ prolapse. Historically, the long term result of these surgeries using the patient's own tissue for the repair, has been disappointing for both the patients and the surgeons. Recurrence of prolapse after standard autologous tissue repairs has been reported to be as high as about thirty percent to about forty percent.

Many current methods for pelvic reconstruction use instruments designed for laparoscopic surgery. These devices allow the surgeon to suture or anchor tissue, or to staple a patch or graft material into place. While laparoscopic instruments may be effective for laparoscopy when used under direct visualization, they tend to be less effective when used used in conditions of limited space and visualization, e.g., the vagina. More specifically, when laparoscopic instruments are used for vaginal surgery, there is a lack of tactile assistance or feedback when working from the end of an instrument. In addition, laparoscopic instruments are rigid and therefore not suited to the angles and planes encountered in vaginal surgery.

Methods, techniques and devices were developed that use a perineal approach. In these techniques, needles or carriers are placed through the skin of the perineum (outside the vagina) and into the pelvis and vagina. Once in position, graft material is attached to the needles which are drawn brought back out to the external skin, pulling the graft into position.

Moreover, these related art instruments are difficult to use with a perineal approach. Moreover, as the perineal approach is not widely taught, or familiar to many surgeons it is not a general skill of most surgeons, and it requires passage of a needle/carrier blindly through a great distance of tissue. Therefore, the difficulty of these techniques and related art devices limit their use to a very few specialists who are able to perform them, thereby limiting the availability of the treatment. Furthermore, this percutaneous approach has resulted in additional possible surgical complications, including infections, surrounding organ injuries, and painful scarring.

Other currently available methods and instruments available use a more traditional and familiar vaginal approach. These are generally sold as a kit, which include rigid devices used to aid in the attachment of graft materials. The graft is preformed and specific to the repair being done, i.e., anterior, posterior or apical. Currently available methods and instruments for the vaginal approach to prolapse repair utilize surgical skills and anatomical landmarks familiar to most gynecologists. However, the cost associated with the kits, the generally rigid and unwieldy nature of these devices render these kits problematic.

Therefore, there is a need for a device, method and/or system that addresses the above and other problems.

SUMMARY OF THE INVENTION

Accordingly, the invention is directed to a medical device, method and system thereof that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.

An advantage of the invention is to provide a flexible finger-tip medical device for treatment that is configured to provide tactile feedback.

Another advantage of the invention is to provide a modular medical device that provides one robust tool allowing for different modular heads, e.g., visualization head, suture head, staple head, tag head, and combinations thereof.

Yet another advantage of the invention is to provide a device where a user not under visual would be able to locate the operating end based on orientation with one or more fingers.

Still yet another advantage of the invention is a medical device having stability of the and alignability along an axis of one or more of finger, hand, and arm, thereby allowing a using to accurately orient the operable end without the need of direct visualization.

Yet still another advantage of the invention is to provide a direct way to secure sutures and anchors in the vaginal approach to female pelvic organ prolapse repair.

Another advantage of the invention is its simplicity when used with a button or latch mechanism to deploy the anchor or tag.

Yet still another advantage of the invention is to provide a medical device with tactile feedback.

Another advantage of the invention is providing a flexible wire, flexible shaft, or other flexible mechanism allowing it to be used through small incisions and placed anywhere the fingertip can reach, not limited by a rigid or thick shaft.

Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of embodiments of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.

One embodiment is directed towards a device having a two finger sheath and having at least one open finger, thereby allowing the user to have tactile dexterity to effectively map the surgical area by finger tip. The two finger sheath provides stability of the device and alignability of the device along an axis of the hand or arm. Other embodiments include at least one closed end finger sheath to allow the user to effectively and precisely secure an anchor to the patient. In other embodiments, the sheath may be configured to only one finger, two fingers or three fingers. Still other embodiments include releasable attached devices to the sheaths which can assist the user in placing sutures.

In other embodiments, the device includes a kit, which contains at least two finger sheaths, a shaft or cable, a cylinder, a tapered ridge, and anchors and/or sutures.

The device is configured to allow a user to traverse a tortuous anatomy and also configured to have a mechanism to operate the operating unit at the same end as the operating unit or an end opposite to the operating unit and external to the patient.

In one embodiment, an exemplary use for the device is for the repair of female pelvic organ prolapse. A vaginal approach is preferred, but is difficult because of limited space and visualization. In this situation, and other surgical circumstances, the anatomical locations are easily accessible to fingertips, but less accessible using currently available unwieldy and rigid instruments. The device of this invention may allow access for the surgeons' fingers to be used to place a suture, anchor, tag, or sensor directly into the desired position by way of the vaginal approach and through small incisions and would allow the surgeon to map the surgical area. The instrument would allow precise placement of suture and/or anchors, which, may be used with autologous tissues or graft materials.

Biocompatible surgical mesh and medical patches may be attached to various portions of a body with the device, e.g., with anchors, sutures, staples out an operating unit of the device.

Reference will now be made in detail to an embodiment of the present invention, example of which is illustrated in the accompanying drawings.

FIG. 1 illustrates a flow diagram highlighting aspects of a method according to an embodiment of the invention.

Referring to FIG. 1, the method is generally depicted as reference 100. The method includes creating an incision 102 at a desired situs, e.g., anterior vaginal mucosa, posterior vaginal mucosa, or vaginal apex. It is noted that the device and method may be used at other locations and for other uses. For example, the device may be used for setting markers or tags in orthopedic and neurosurgical procedures where navigation systems are used to guide placement of implants and the like. The mucosa is dissected 104 sharply and/or bluntly away from the underlying connective tissue plane (endopelvic fascia). Deficiency or breakdown of this connective tissue layer is what allows the prolapse and bulging of the vaginal walls and underlying pelvic organs into the vagina to occur, i.e., the bladder from anteriorly (cystocele), the rectum from posteriorly (rectocele), the uterus or intestines from superiorly (uterine prolapse or enterocele), on the vaginal walls from laterally (paravaginal defect).

The connective tissue plane can be traced to the pelvic side wall where substantial ligamentous and fascial structures exist and serve as landmarks and anchor points 106. The mapping may be done while the device is being used by the user, e.g., with one or more finger tips. After a map of the surgical area is developed, the device on two or more finger(s) is inserted the device into the vagina 107. The device is arranged on a co-axial orientation to an axis of the arm and/or hand to aid in orientation. Anchors and sutures are generally set into the sacrospinous ligament, arcus tendentious, obturator fascia and coopers ligament 108. Following this plane through a small vaginal incision to the pelvic sidewall is a basic gynecologic surgical maneuver. Once this plane is developed for the patient, the anatomical landmarks are easily palpable and the sacrospinous ligament, arcus tendinous, Cooper's ligament and obturator fascia are easily identified though very difficult to visualize.

The device may be used with surgeons' second and third fingers to aid in location and placement to a desired location on the pelvic wall and these fingers provide tactile feedback via an exposed fingertip. Moreover, as the sheath utilizes at least two fingers the orientation the stability of the device is readily maintained. e.g., middle finger and the ring finger; index finger and middle finger; or little finger and the ring finger. In this preferred embodiment, the user aligns the devices via their fingers, hand, and/or arm to ensure proper placement without sight. The device is not offset from fingers, hand, and/or arm, e.g., along a central axis, thereby allowing alignment even though there is no visualization.

Next, an anchor, with attached suture, is delivered from the device exactly to the desired location by pushing the button at the opposite end of the device. In a preferred embodiment, this is done while the surgeon is still in contact with the pelvic wall. With the anchor exposed, and pressure delivered 110 at the closed finger-tip end, the device will set the anchor into the tissue at the desired location in the pelvic wall. In a preferred embodiment, the anchor and mesh are configured to repair, secure, or reattach the underlying connective tissue, or anchor graft material that substantially supports the prolapsed organs.

Optionally, sutures may be attached to these anchors and can be used to support the vaginal wall itself, with or without the use of a graft. With the safety of vaginal mesh under scrutiny by the FDA, many surgeons are returning to use mesh-free repairs. The device described herein would make those procedures much easier.

Alternatively, anchors and sutures in the sacrospinous ligament, arcus tendentious, obturator fascia and/or coopers ligament could also be used to suture graft material over the deficient connective tissue plane for a graft augmented repair. Alternatively, anchors without sutures may be used to directly tack graft material to the desired location.

In still other embodiments, the operating unit of the device may be modified with devices known in the art. For example, the operating unit may include a scope to give active visual aid to the surgeon. In another example, the operating unit of device may include a endoscopic suture device or anchor device configured to secure the graph or support an prolapsed area. By way of example, the endoscopic suture systems may be incorporated in the operating unit and include systems as known in the art, e.g., as disclosed in U.S. Pat. Nos. 5,364,408; 5,458,609; 5,478,344; 5,540,704; 5,575,800; 5,578,044; 5,662,664; 5,700,272; 5,713,910; 5,741,277; 5,741,279; 6,048,351; 7,582,096, and U.S. Patent Application Publication Nos. 2010/0217282; 201110092985 and 2011/0092991, all of which are herein incorporated by reference.

The suture device may be used in laparoscopic procedures. The suture device, and in particular the head of the device, may be used with the present invention by attaching the head of the suture device to the finger sheaths of the present invention. In general, the suture device automatically throws, catches and retrieves a suture through the head of the device. An example of a suture device is described in U.S. Pat. Nos. 5,741,277 and 7,582,096, which are incorporated herein by reference.

FIG. 2 illustrates a perspective view of an endoscopic suture device according to an embodiment of the invention.

Referring to FIG. 2, an apparatus is generally depicted as reference number 200. The apparatus 200 includes a connection mechanism 202 fixed to an end portion of the tubular member 204. A finger sheath (not shown), described with reference to FIGS. 7A-15 is utilized with this device 200 and configured to be coupled to the device 200 via the connection mechanism 202 as described with reference to FIGS. 13-15.

The apparatus 200 includes the body 204 having a first half 206 and a second half 207. A needle slot 208 is utilized to deploy a cannula 210 out of the cannula body 204. The cannula 210 can be utilized with other instruments as known in the art. For example, the cannula 210 is utilized to deploy a needle and sutures (not shown). Alternatively, other secondary devices may be delivered through the cannula 210, e.g., visualization devices.

FIG. 3 illustrates a perspective view of a needle catch mechanism with a needle and a phantom view of a cannula body according to another embodiment of the invention.

Referring to FIG. 3, the suture system is generally depicted as reference number 300. The suture system includes a first half 302 and a second half 304 configured to form a body 306. The system 300 includes a connection mechanism 305 fixed to an end portion of the tubular member 306. A finger sheath (not shown), described with reference to FIGS. 7A-15 is utilized with this device 300 and configured to be coupled to the device 300 via the connection mechanism 305 as described with reference to FIGS. 13-15.

A surgical needle 308 includes a needle tip 310 and a needle body 312, and a suture 314. A retainer lever 316 is pivotally mounted on a shaft 318 and is biased to a neutral position by a spring 320 or other suitable mechanism. A needle guide track terminates in an exit opening 322. A flexible needle driver guide track and the needle guide track combine to form a continuous pathway in which a flexible needle driver with a needle driver tip is slidably disposed. The needle 308 is inserted through the exit opening 322. The needle 312 and the suture 314 are inserted into the needle guide track until the needle tip 310 is positioned adjacent to the exit opening 322. It may be seen that during insertion into the needle guide track, the needle 308 causes the retainer lever 316 to rotate pivotally on the shaft 318 to a retracted position. In operation, an actuator (not shown) is operated to advance the needle 308.

To retrieve the needle 308 and the suture 314 the cannula body 306 is placed in the surgical field and maneuvered to guide the needle tip 310 and needle shaft through an opening in a needle catch, which includes the opening and a catch bottom. The flexible needle driver is advanced in the needle guide track, engaging and pivotally rotating the retainer lever 316 and pinching and capturing the needle body 312 between the retainer lever 316 and a catch bottom. The needle 308 and the suture 314 may then be removed from the surgical field through the surgical trocar or other suitable instrument. To release the needle 308 from being pinched by the retainer lever 316 and the catch bottom, the flexible needle driver is retracted, allowing the retainer lever 316 to return to the neutral position, thus freeing the needle 308.

In still other embodiments, an apparatus such as a suture device may be modified with aspects of the invention including a finger sheath and connection mechanism to provide a device that allows for advantages of the invention. Examples of devices that may be modified are disclosed in U.S. Pat. Nos. 7,828,189; 7,828,798; and 7,789,878; and U.S. Publication Nos. 2010/0094083; 2010/0217282; 2010/0274265; 2011/0040308; 2010/0147921; 200610036232; 200910248046; and 2009/0259233, and are each incorporated by reference, in particular, the portions of the disclosures describing the head of the endoscopic stitching device. More specifically, each of the foregoing may be modified and adapted for use with a connection mechanism 305 fixed to an end portion of any of the foregoing devices. A finger sheath (not shown), described with reference to FIGS. 7A-15 is utilized with this any of the foregoing modified devices and configured to be coupled to the device via the connection mechanism 305 as described with reference to FIGS. 13-15.

FIG. 4 illustrates a cross-section view of a stitching device in an open condition according to another embodiment of the invention. FIG. 5 illustrates a cross-section view of the stitching device of FIG. 4 in a closed condition. FIG. 6 illustrates a bottom of the stitching device of FIG. 4.

Referring to FIGS. 4-6, a suture system 400 includes a needle 402 coupled to a first end 404, the needle is configured to be received by a second end 406. A recess is formed in the second end 406 to receive a portion of the needle 402. The first end 404 and second end 406 are maintained in an open position by an actuating mechanism. The actuating mechanism includes a first slot 408 in the first end 404, a second slot 410 on the second end 406, and a pin 412 is in communication with the first slot 408 and second slot 410. The pin 412 is coupled to an actuator 414, e.g., cable, rod and the like, configured to move the pin from a first position to a second position as indicated by arrow 416, thereby moving the first end 404 and second end 406 from a closed position to an open position and vice versa.

Referring to FIG. 5, the suture system 400 is in a closed position. The closed position is achieved by moving the actuator 414 from a first position to a second position as indicated by arrow 417 to open the device.

FIG. 7A illustrates a top view of a device according to another embodiment of the invention.

Referring to FIG. 7A, the assembly is generally depicted as reference number 700. The assembly 700 includes an actuator 702 configured to actuate the delivery of an anchor from a unit 704 at the opposite end of the device 700. The unit 704 is coupled to the flexible shaft 706 and both are constructed from materials known in the art, e.g., thermoplastic material. The shaft 706 may be any length, e.g., equal to, greater than or less than the length of a finger sheath unit 708. An anchor (not shown) is delivered from the unit 704 at a distal end of the instrument when the actuator 702 is actuated. Furthermore, the user may insert additional anchors into a portion of the shaft 706 during use by removing the actuator 702, inserting an anchor and reinserting the actuator 702. In addition, additional anchors may be added to the unit 704 during or before use. e.g., another unit 704 can be removed and recoupled to the shaft 706 as a cartridge attachment or the unit 704 may be refilled. The actuator 702 may be a plunger or other actuator mechanism 702 configured to deliver an anchor from the unit 704. For example, the actuator may be a cable, remote control, spring driven, hydraulic or other pressure driven mechanism, or combinations of the same and the like.

The finger sheath unit 708 is removably coupled to the shaft 706 and includes at least two finger slots 710 and 712 configured to receive at least a portion of user's fingers. It is noted that finger slots 710 and 712 may include a supplemental medical devices rather than a finger slot or in addition to a finger slot. e.g., a cutter, visualization aids, storage, laser ablation devices and the like, may be coupled to at least one of the finger slots 710, 712 or as an additional feature adjacent to one of the finger slots 710, 712. A visualization aid may include radio opaque (RO) markers, camera with or without light, or other visualizations aids as known in the art. The finger slots 710 and 712 are oriented to be co-axial and/or in substantially the same plane with the unit 704 and/or centered over the unit 704. The co-axial, same plane and/or centered orientation enables a user to align the unit 704 without the need for visualization or with poor visualization. In one embodiment, one of the at least two finger slots is not a finger slot, but rather a supplemental treatment device or visualization aid. Moreover, the two finger slots may include one finger slot, two finger slots or three finger slots.

In use, the apparatus 700 is guided to the desired treatment situs with a user's fingers in the finger sheaths 710 and 712 to a treatment situs. In this embodiment, the finger sheath 712 is an open end finger sheath and the finger sheath 710 is a closed end finger sheath. The open end of finger sheath 712 allows for accurate tactile feedback with a user's finger. The closed end of the finger sheath 708 allows for additional pressure and stability to be exerted on an anchor during insertion and when it is in place. It is noted that each of the finger shealths may be adjustable to receive a plurality of different finger sizes, e.g., the diameter of the finger sheath may be adjustable with a ratchet or other mechanism. Moreover, the finger sheath may be configured to cover only a quarter or less of an end portion of predetermined finger of a predetermined user.

It is also noted that the finger sheath 710 and finger sheath 712 may be arranged in different planes with respect to each other. That is, the first finger sheath 710 and second finger sheath 712 may be arranged at any angle from 0 to 360 degrees around the shaft 706. Moreover, the finger sheaths may be arranged at an angle from the shaft, e.g., about 1 degree to about 20 degrees or greater. The first finger sheath 710 may have a portion, e.g., the distal end, located proximally from the second finger sheath 712. Instill other embodiments, three finger sheaths may used. In this embodiment, the finger sheath 710 and finger sheath 712 are arranged in substantially the same plane with respect to each other.

The unit 704 is also coupled to the shaft 706 (as shown in FIG. 9). The unit 704 is configured to deliver an anchor to a treatment situs upon actuation of the actuator 702.

In this preferred embodiment, the distal end of the unit 704 is terminated at about the same distance as the closed end of the finger sheath 710. This termination distance allows for leverage in placing a suture, anchor or other item, assists in increasing the effect of the force exerted on the device 700, and permits precise location when visualization is not available or poor. Of course, the distal end of the unit 704 may be located at a distance proximal or distal to either of the finger sheaths 710, 712.

In another embodiment, the actuator 702 may be placed directly adjacent the unit 704 and there is no tubular member 706 (not shown). This compact configuration is actuated by a user with the same hand as in the finger sheath 708 rather than a different hand.
